Fluxgate-Based Residual Current Sensors

KEMET Fluxgate-Based Residual Current Sensors are high-sensitivity DC-AC current sensors that can detect DC and AC leakage current. If a DC fault occurs, Pin 4 will change its state from low level to high impedance. If an AC fault occurs, Pin 5 will change its state from low level to high impedance. These PCB-mounted sensors have a test coil for checking the sensor's operation, and by inputting a signal from the outside, it is possible to pass a test current to the test coil. The sensors also output a digital signal if they detect any leakage current. KEMET Fluxgate-Based Residual Current Sensors operate in a temperature range of -40°C to +85°C or +105°C. These modules are ideal for wall boxes and in-cable control and protection devices (IC-CPD).
